libc/setjump: Align stack at 16-bytes before function call

This is required by amd64 ABI. Comments were added where stack was
"accidentally" properly aligned. The problem manifested on with a
bus error when built by clang.

While here, preserve the floating float exceptions flags. Per POSIX,
siglongjump() shall be equivalent to longjump() except that it must
match sigsetjump() instead of setjump() and except for the effect on the
signal mask. Therefore it should preserve the FP exception flags.

Also add the GNU-stack notes, all libc object files are supposed to have
them (although I am pretty sure they don't).

rename amd64 architecture to x86_64

The rest of the world seems to call amd64 x86_64. Bite the bullet and
rename all of the architecture files and references. This will
hopefully make pkgsrc build

This reverts commit c1543a890188d397acca9fe7f76bcd982481a763.

I'm reverting it because:
1) the change didn't get properly discussed
2) it was based on false premises:
"The rest of the world seems to call amd64 x86_64."
3) no pkgsrc bulk build was done to test the change
4) the original committer acted irresponsibly by committing
such a big change just before going on vacation.
